SHIPPENSBURG - Saturday is National Hot Dog Day and locally there will be at least one location where hot dog lovers will be able to enjoy their favorite delicacies.

The Philly Pretzel Factory, known for its pretzels, is having a special deal on their pretzel dogs for $1 in honor of the "holiday" Saturday. The Philly Pretzel Factory pretzel dog is a hot dog covered with american cheese and baked inside a pretzel.

"Once you have it, it's so good, you'll come back," .

The idea started about four years ago on the heels of National Pretzel Day. In 2008, Philly Pretzel Factory businesses began giving away pretzels on National Pretzel Day, held April 26. With their trademark menu item having its own day in late April, Philly Pretzel Factory officials began examining their expanding menu and realized that the pretzel dog was one of the more popular items on the menu. Upon that realization, officials wondered how to promote the pretzel dog and soon they heard about National Hot Dog Day, held in mid-July.

"We thought we should do something along the lines of that," said Adam Terranova, marketing manager for Philly Pretzel Factory.

The first $1 pretzel dog event on National Hot Dog Day occurred in 2014 and Terranova said the event becomes a little more popular every year and has "continued to grow each and every year for us" to the point where people are lining up outside various stores early in the morning for the pretzel dogs.

“After offering $1 pretzel dogs for National Hot Dog Day for the first time in 2014, the day proved to be a great success across the system,” Dan DiZio, CEO and co-founder of Philly Pretzel Factory said in a press release. “We are so ingrained in the communities we serve that it is a natural fit to want to give back to our loyal fans.”

"I hope people come out if they haven't tried one and come back for more," Terranova said.
